OBJECTIVE: This study aimed to investigate the validity and reliability of the Turkish version of the Children's Home Inventory for Listening Difficulties - (C.H.I.L.D) questionnaire. METHODS: The study included 121 children with cochlear implants and their families aged 3-12 years and 171 children with normal hearing and their families. Confirmatory factor analysis (C.F.A.) was used to assess construct validity, Cronbach's alpha was used to analyze internal consistency and test-retest reliability was also investigated. RESULTS: The reliability coefficients of the entire C.H.I.L.D family member (C.H.I.L.D-FM) and children version (C.H.I.L.D-C) were 0.983, 0.978, and Cronbach's coefficients were 0.992, 0.992, and the corrected item-total correlations increased from 0.989 to 0.994 and from 0.988 to 0.994, respectively. The scale's construct validity was excellent, according to the CFA analyses. The goodness-of-fit indexes (for the parent's version 0.892 and for the child's version 0.867) demonstrated a good fit for the single-factor construct, with only the normed fit index revealing an acceptable fit. CONCLUSION: The Turkish version of the C.H.I.L.D is a reliable and valid evaluation test for children and their family members.

OBJECTIVES: To study the voice acoustic parameters of congenitally deaf children with delayed access to sounds due to late-onset cochlear implantation and to correlate their voice characteristics with their auditory performance. METHODS: The study included 84 children: a control group consisting of 50 children with normal hearing and normal speech development; and a study group consisting of 34 paediatric cochlear implant (CI) recipients who had suffered profound hearing loss since birth. According to speech recognition scores and pure-tone thresholds, the study group was further subdivided into two subgroups: 24 children with excellent auditory performance and 10 children with fair auditory performance. The mean age at the time of implantation was 3.6 years for excellent auditory performance group and 3.2 years for fair auditory performance group. Voice acoustic analysis was conducted on all study participants. RESULTS: Analysis of voice acoustic parameters revealed a statistically significant delay in both study groups in comparison to the control group. However, there was no statistically significant difference between the two study groups. DISCUSSION: Interestingly, in both excellent and fair performance study groups, the gap in comparison to normal hearing children was still present. While late-implanted children performed better on segmental perception (e.g. word recognition), suprasegmental perception (e.g. as demonstrated by objective acoustic voice analysis) did not progress to the same extent. CONCLUSION: On the suprasegmental speech performance level, objective acoustic voice measurements demonstrated a significant delay in the suprasegmental speech performance of children with late-onset CI, even those with excellent auditory performance.

An increasing number of young infants, as early as six months of age with congenital hearing loss receive cochlear implantation, and it is probable that many of these patients will require revision surgery later in life. The possibility of explantation of the cochlear electrode and reimplantation may cause damage to the cochlea, compromising the speech perception outcome in revision implant is of concern. There is only one prior temporal bone histopathology study to look at the outcome of revision surgery and no prior study evaluating revision cochlear implantation that used the round window approach. We conducted a histopathological study of four temporal bone specimens from four patients who underwent revision cochlear implantation and when available post-operative speech perception tests were evaluated. In all cases, the reimplanted electrode followed into the same fibrous sheath without evidence of additional intracochlear damage due to revision surgery. The intracochlear damage from the initial cochlear implantation appears to be a more important factor in outcomes rather than changes associated with explantation and reimplantation.

BACKGROUND: Device activation typically occurs four weeks post cochlear implant surgery. Emerging evidence suggests earlier activation is feasible and beneficial, giving patients quicker access to sound and rehabilitation. OBJECTIVES: Assess current literature for effects of early cochlear implant activation. METHODS: Electronic searches of Medline/PubMed, AMED, EMBASE, CINAHL and the Cochrane Library following PRISMA guidelines. Studies investigating any aspect of early activation were included for review. RESULTS: From 15 studies, 625 patients received early activation, compared with 243 patients in the control groups. Early activation was considered as within 7 days post-operatively with 12 studies reporting within 1 day post-operatively, compared with standard activation of 9-46 days post-operatively in the control group. Some studies indicated earlier low levels of impedance in the early activation group. Magnet strength adjustment or off-ear processor wear was often recommended within the early activation cohort. Complication rates were low in both groups. Early activation improved patient satisfaction and anxiety levels without detriment to speech recognition or rehabilitation. CONCLUSION: Early cochlear implant activation is feasible and allows patients with no contraindications, earlier access to auditory perception and rehabilitation and reduces anxiety linked to delay in activation. Further evidence is required to monitor long-term effects of early activation.

OBJECTIVES: Electrode impedance measurements from cochlear implants (CI) reflect the status of the electrode array as well as the surrounding cochlear environment, and could provide a clinical index of functional changes with the CI. The goals of this study were to examine (1) the impact of electrode array type on electrode impedance, and (2) the relationship between electrode impedance and short-term hearing preservation and speech recognition outcomes. METHODS: Retrospective study of 115 adult hearing preservation CI recipients of a slim modiolar or slim straight array. Common ground electrode impedances, pre- and post-operative hearing thresholds and CNC word recognition scores were retrieved. RESULTS: Electrode impedances were significantly higher for recipients of the straight electrode array. Within individuals, electrode impedances were stable after the first week post-activation. However, increased standard deviation of electrode impedances was associated with greater loss of low frequency hearing at initial activation, and with poorer speech recognition at 6 months post-implantation. CONCLUSIONS: Results demonstrate that electrode impedances depend on the type of implanted array. Findings also suggest that there may be a role for the variability in electrode impedance across electrodes as an indicator of changes in the intracochlear environment that contribute to outcomes with a CI.

OBJECTIVES: Changes in vestibular function have been demonstrated following cochlear implantation (CI). The functional impact of these changes on CI performance has not been well-studied. We sought to assess whether caloric changes postimplantation could predict CI performance. METHODS: Retrospective review of a prospectively collected database at a tertiary care hospital. Patients who underwent CI over a 22-year period (1999-2021) and had videonystagmography (VNG) testing pre- and postimplantation were included. Caloric responses were compared pre- versus post-implantation, and assessed for their ability to predict CI performance as evaluated using AzBio +10 decibels signal-to-noise ratio (dB S/N) scores. RESULTS: 43 CI recipients were included. There was a significant difference in the average maximal slow-phase velocity in response to caloric irrigation in the implanted ear pre- versus post-operatively (21.2 vs. 18.5 deg/s; = 0.02). Controlling for age and pre-implantation speech recognition performance, pre- and post-implantation caloric responses in the implanted ear significantly predicted CI performance at 0-6 months and >6 months post-implantation. Caloric changes following implantation were not significantly correlated with CI performance. CONCLUSION: CI impacts vestibular function as evidenced by changes in caloric responses. Vestibular function pre- and possibly post-CI may be clinically useful metrics for predicting some proportion of CI performance variability.

OBJECTIVE: To compare vestibular outcomes in cochlear implant (CI) surgery, between robotic-assisted insertion of the electrodes versus manual insertion. METHODS: We performed a monocentric retrospective study. From March 2021, the robotic system RobOtol© was used for all CI cases. We compared this robotic-assisted insertion group with a manual insertion group of patients who received a CI between July 2020 and March 2021. Primary objective was vestibular outcome. We used objective vestibular function tests: caloric testing, Vestibular Evoked Myogenic Potential (VEMP), and Video Head Impulse Test (VHIT). Secondary objectives were postoperative complications including patient-reported postoperative vertigo. RESULTS: We found no statistically significant difference between the two groups in terms of caloric testing, VEMP or VHIT outcomes. In patient-reported outcomes, there was significantly more vertigo in the manual insertion group compared with robotic-assisted insertion. CONCLUSION: It is hypothesized that a non-traumatic insertion would cause less vestibular dysfunction postoperatively. Larger prospective studies are required to determine whether robotic-assisted CI insertion has a significant impact on vestibular outcomes in CI surgery.

OBJECTIVES: To propose an automated fast cochlear segmentation, length, and volume estimation method from clinical 3D multimodal images which has a potential role in the choice of cochlear implant type, surgery planning, and robotic surgeries. UNLABELLED: Two datasets from different countries were used. These datasets include 219 clinical 3D images of cochlea from 3 modalities: CT, CBCT, and MR. The datasets include different ages, genders, and types of cochlear implants. We propose an atlas-model-based method for cochlear segmentation and measurement based on high-resolution CT model and -value. The method was evaluated using 3D landmarks located by two experts. UNLABELLED: The average error was mm and the average time required to process an image was seconds (<0.001). The volume of the cochlea ranged from 73.96 mm to 106.97 mm, the cochlear length ranged from 36.69 to 45.91 mm at the lateral wall and from 29.12 to 39.05 mm at the organ of Corti. UNLABELLED: We propose a method that produces nine different automated measurements of the cochlea: volume of scala tympani, volume of scala vestibuli, central lengths of the two scalae, the scala tympani lateral wall length, and the organ of Corti length in addition to three measurements related to -value. UNLABELLED: This automatic cochlear image segmentation and analysis method can help clinician process multimodal cochlear images in approximately 5 seconds using a simple computer. The proposed method is publicly available for free download as an extension for 3D Slicer software.

Cerebellopontine angle (CPA) meningiomas commonly involve the internal auditory canal (IAC). We report a case of a 68-year-old lady with idiopathic profound bilateral deafness with a meningioma which was discovered on workup for cochlear implantation. We performed simultaneous excision of her CPA and IAC meningioma with insertion of a cochlear implant (CI). She regained functional hearing with marked improvement in quality of life. Intraoperative electrophysiological testing can be used to confirm preservation of the cochlear nerve enabling simultaneous implantation which is preferable for clinical and logistical reasons. This creates an option for hearing rehabilitation at the time of IAC/CPA tumour surgery in appropriate patients.

OBJECTIVES: Quality of life plays an important place in the psychosocial development of children with Cochlear Implants (CI). We assesd health-related quality of life (HRQoL) in children with CI and in hearing children and determined relationships between HRQoL and other developmental characteristics (social-emotional development, Theory of Mind (ToM), spoken language skills). METHODS: A longitudinal study was conducted including children with CI and hearing children. We used instruments that are widely employed and have been validated for research. At time 1 social-emotional development, ToM and spoken language skills were assessed.HRQoL was assessed using the generic KINDL questionnaire, as was social-emotional development, 2.5 years later (time 2). RESULTS: No significant difference was seen in HRQoL between hearing children and children with CI. We show that the age of detection, the age of hearing care, and the start of early intervention are not related to HRQoL of children with CI, but relationships with some domains of social-emotional development are evident. CONCLUSIONS: This study highlights the importance of targeted intervention not only to improve spoken language skills at preschool age, but also strengthen social-emotional and social-cognitive competences.

OBJECTIVES: This study investigates the role of sentence stress on the comprehension of sentences with clitic pronouns (unstressed morphemes and a typical feature of Romance languages) by children with cochlear implants (CIs). METHODS: Thirteen children (seven girls) with CIs and 15 children (seven girls) with NH between eight and 12 years who are monolingual speakers of Brazilian Portuguese participated on a computerized sentence comprehension task that involved manipulation of stress placement of possible antecedent words to clitic pronouns. RESULTS: Children with CIs were significantly less accurate than children with NH in comprehending sentences with clitics, regardless of sentence stress. For children with NH, stress on the correct antecedent significantly increased sentence comprehension accuracy. For children with CI, there was no significant effect of sentence stress on selecting the correct antecedent for clitic pronouns. DISCUSSION: Comprehension of sentences with clitic pronouns is challenging for children with CIs and this challenge holds cross-linguistically. Furthermore, children with CIs do not use prosodic information to support comprehension of sentences with clitics similarly to NH children. CONCLUSION: Language-specific syntactic, morphosyntactic, and prosodic contrasts affecting sentence comprehension need to be assessed in children with CIs to plan an effective intervention.

OBJECTIVES: The purpose of this study was to determine the prevalence of ceiling effects for commonly used speech perception tests in a large population of children who received a cochlear implant (CI) before the age of four. A secondary goal was to determine the demographic factors that were relevant for predicting which children were more likely to reach ceiling level performance. We hypothesize that ceiling effects are highly prevalent for most tests. DESIGN: Retrospective chart review of children receiving a CI between 2002 and 2014. RESULTS: 165 children were included. Median scores were above ceiling levels (≥90% correct) for the majority of speech perception tests and all distributions of scores were highly skewed. Children who were implanted earlier, received two implants, and were oral communicators were more likely to reach ceiling-level performance. Age and years of CI listening experience at time of test were negatively correlated with performance, suggesting a non-random assignment of tests. Many children were re-tested on tests for which they had already scored at ceiling. CONCLUSIONS: Commonly used speech perception tests for children with CIs are prone to ceiling effects and may not accurately reflect how a child performs in everyday listening situations.

OBJECTIVES: To review the decision-making paradigm in the recommendations of BCI and aMEI overlapping candidacy for patients with conductive or mixed HL, and to determine if there are differences in hearing and quality of life outcomes between these implantable hearing devices. METHODS: Retrospective data from patients receiving BCI or aMEI in the past decade were analysed. Patients were grouped into: 1. BCI candidates, 2. BCI or aMEI candidates, and 3. aMEI candidates. We compared outcomes and examined the impact of BC threshold, age at implantation, and duration of hearing loss on candidacy. RESULTS: 89 participants were included: 30 BCI, 37 aMEI, and 22 BCI or aMEI candidates. All groups performed similarly in aided sound field threshold testing. BCI group had lower speech scores in quiet compared to 'BCI or aMEI.' No significant differences were found in APHAB global scores. BC threshold, duration of hearing loss, and age at implantation had no significant effects. DISCUSSION: Outcomes were generally similar across groups, except for higher effective gain in the aMEI group. CONCLUSION: Our proposed patient pathway and decision-making approach facilitate candidate selection for aMEI and BCI, aiming to optimise outcomes.

PURPOSE: Patient suitability for cochlear implant (CI) devices compatible with magnetic resonance imaging and CI processor configuration is dependent on their retro-auricular skin flap thickness. This is typically measured intra-operatively using a needle and therefore patients are not guaranteed their implant of choice prior to surgery. We aimed to identify an accurate method to measure skin flap thickness pre-operatively to streamline CI selection and simplify the consent process. METHODS: Blinded prospective skin flap thickness measurements for patients undergoing CI surgery were recorded using pre-operative computed tomography (CT) and ultrasound (US), and intraoperative needle measurement. RESULTS: Fifty-six adult patients (36 females, 20 males; mean age 59 years) were included. The mean flap thickness was measured highest by CT (6.9 mm, 95% CI 6.5-7.3 mm), followed by US (6.3 mm, 95% CI 5.9-6.7 mm) and lastly needle (5.5 mm, 95% CI 5.1-5.9 mm) ( < 0.0001). A strong positive correlation ( < 0.001) was noted between all three modalities: CT vs needle ( = 0.869), US vs needle ( = 0.865), and CT vs US ( = 0.849). CONCLUSION: Accurate, non-invasive measurement of skin flap thickness prior to CI surgery can be achieved using CT or US. We recommend the routine use of US in the outpatient clinic to minimise unnecessary radiation exposure.

PURPOSE: Cochlear implant (CI) recipients struggle to hear in competing background noise. ForwardFocus is a spatial noise reduction setting from Cochlear Ltd. (Sydney) that can simultaneously attenuate noise from multiple sources behind the listener. This study assessed hearing performance with ForwardFocus in an off-the-ear (OTE) sound processor. METHOD: Twenty-two experienced adult CI recipients participated. Speech reception data was collected in fixed noise acutely in the clinic. After three to five weeks take home experience, subjective impressions were recorded, and evaluations were conducted for speech reception in quiet and roving noise. RESULTS: Group mean speech reception thresholds (SRT) were below 0 dB in two spatially-separated noise test conditions when using ForwardFocus in the OTE sound processor. SRT were -8.5 dB (SD 2.9) in 4-talker babble roving in a rear hemi-field (S0Nrearhemi) and -3.9 dB (SD 3.3) in 12-talker babble presented laterally and behind (S0N3). Results in S0N3 were significantly better with ForwardFocus On ( = 0.0018). Subjective ratings with the OTE were comparable to, or better than, with their walk-in BTE or OTE sound processor. CONCLUSIONS: ForwardFocus provides significant benefits for speech recognition in competing background noise in an OTE sound processor. These results support clinicians in counselling CI recipients on potential sound processor options to consider.

OBJECTIVE: Identify and evaluate the effectiveness of methods for improving postoperative cochlear implant (CI) hearing performance in subjects with single-sided deafness (SSD) and asymmetric hearing loss (AHL). DATA SOURCES: Embase, PubMed, Scopus. REVIEW METHODS: Systematic review and narrative synthesis. English language studies of adult CI recipients with SSD and AHL reporting a postoperative intervention and comparative audiometric data pertaining to speech in noise, speech in quiet and sound localization were included. RESULTS: 32 studies met criteria for full text review and 6 (n = 81) met final inclusion criteria. Interventions were categorized as: formal auditory training, programming techniques, or hardware optimization. Formal auditory training (n = 10) found no objective improvement in hearing outcomes. Experimental CI maps did not improve audiologic outcomes (n = 9). Programed CI signal delays to improve synchronization demonstrated improved sound localization (n = 12). Hardware optimization, including multidirectional (n = 29) and remote (n = 11) microphones, improved sound localization and speech in noise, respectively. CONCLUSION: Few studies meeting inclusion criteria and small sample sizes highlight the need for further study. Formal auditory training did not appear to improve hearing outcomes. Programming techniques, such as CI signal delay, and hardware optimization, such as multidirectional and remote microphones, show promise to improve outcomes for SSD and AHL CI users.

OBJECTIVE: To investigate whether revision surgery with the same device results in a change in three key indicators of electrode positioning: scalar location, mean modiolar distance (), and angular insertion depth (AID). METHODS: Retrospective analysis of a cochlear implant database at a university-based tertiary medical center. Intra-operative CT scans were obtained after initial and revision implantation. Electrode array (EA) position was calculated using auto-segmentation techniques. Initial and revision scalar location, , and AID were compared. RESULTS: Mean change in for all ears was -0.07 mm (SD 0.24 mm; = 0.16). The mean change in AID for all ears was -5° (SD 67°; = 0.72). Three initial implantations with pre-curved EAs resulted in a translocation from Scala Tympani (ST) to Scala Vestibuli (SV). Two remained translocated after revision, while one was corrected when revised with a straight EA. An additional five translocations occurred after revision. CONCLUSIONS: In this study examining revision cochlear implantation from a single manufacturer, we demonstrated no significant change in key indicators of EA positioning, even when revising with a different style of electrode. However, the revision EA is not necessarily confined by the initial trajectory and there may be an increased risk of translocation.

To investigate the postoperative long-term outcomes after an average of 9.2 years following cochlear implantation (CI) in prelingually deafened adults, along with preimplantation factors predicting postoperative outcomes. Twenty-six prelingually deafened adults who underwent CI at >18 years were compared with those who had undergone CI in childhood (<9 years) and were >10 years old. Outcome measures includedhearing thresholds, preoperative and postoperative aided hearing level (HL), speech discrimination score (SDS), and Categories of Auditory Performance (CAP) scores. Correlation analyses were performed on the following: SDS results, aided HL, school attendant status, implant manufacturers, and speech processor models. Improvement was achieved in the aided HL and SDS results, although these results were not better than those of the child group. CAP score was also statistically significantly improved after CI. Statistically significant correlation between the preoperative SDS and postoperative HL with CI results was observed. In other words, the better the preoperative SDS results, the better the postoperative SDS results. Prelingually deafened adults achieved considerable improvement through CI. It is important to understand that patients achieving better hearing with a well-fitted hearing aid and good SDS performance before surgery may be good candidates for CI.

PURPOSE: Cochlear implant (CI) decision-making is particularly challenging for families of children who have residual hearing. Parents of these children may be uncertain about whether the potential benefits of CIs outweigh the risks. This study aimed to understand parents' decisional needs during the decision-making process for children with residual hearing. METHOD: Semi-structured interviews were conducted with parents of 11 children who had received CIs. Open-ended questions were asked to encourage parents to share their experiences about the decision-making process, their values/preferences, and their needs. The interviews were transcribed verbatim and analyzed using thematic analysis. RESULTS: Data were organized according to three key themes: (1) Parents' decisional conflict, (2) values and preferences, (3) decision support and parents' needs. We found that overall parents were satisfied with their decision-making process and the decision support from practitioners. However, parents stressed the importance of receiving more personalized information that considers their specific concerns, values and preferences related to family's circumstances. CONCLUSIONS: Our research provides additional evidence to guide the CI decision-making process for children with residual hearing. Additional collaborative research with audiology and decision-making experts specifically on facilitating shared decision-making is needed to provide better decision coaching for these families.

OBJECTIVES: To audit surgical complications and their management in cochlear implant (CI) recipients in a tertiary care referral otorhinolaryngology center in South India. MATERIALS AND METHODS: Hospital data on 1,250 CI surgeries performed from June 2013 to December 2020 was reviewed. This is an analytical study with data collected from medical records. The demographic details, complications, management protocols and relevant literature were reviewed. Patients were divided into the following five age groups: 0-3 years, 3-6 years, 6-13 years, 13-18 years and above 18 years. Complications were divided into major and minor and complication occurrence was divided into peri-operative, early post-operative, and late post-operative, and the results were analyzed. RESULTS: The overall major complication rate was 9.04% (including 6.0% due to device failure). If the device failure rate was excluded, the major complication rate was 3.04%. The minor complication rate was 6%. DISCUSSION: CI is the gold standard in the management of patients with severe to profound hearing loss with minimal benefit from conventional hearing aids. Experienced tertiary care CI referral and teaching centers manage complicated implantation cases. Such centers typically audit their surgical complications, providing important reference data for young implant surgeons and newer centers. CONCLUSION: Although not bereft of complications, the list of complications and its prevalence is sufficiently low to warrant the advocacy of CI worldwide, including developing countries with low socio-economic status.
